Hi All,

I am new to .Net framework. I was basically a Oracle Developer. I am trying to use tab control for my project. I have a main page with a listview displayed using table control. I display all the records from the database into a listview and once the user selects the edit button for a particular record that needs to be displayed as a normal form on another page with tab controls. So I want to populate the data that retrieved in this listview data into multiple tab controls. I really have no clue how to assign the data from listview to tabcontrol1.textbox, tabcontrol2.textbox and so on.. Can someone help me with this? As this is my first project, I really want to explore more into this. Please let me know if it is not clear.
This is my main page. After I select a particular record, it takes me to a page with tab controls. I have 4 to 5 tab controls on the next page.

Here I want the contractorNumber to be displayed in txtVendorNumber of TabPersonal.

Any help on this is really appreciated.

Solution 1

I looked through your code and it looks like all you need is to add a database lookup in the Page_Load event of the page that has the tab control. You can get the passed in variable by using

VB

Dim contractor As String = Request.QueryString("ID")

Once you have it as a string you can convert it to an integer or whatever data type you need to do the query.

Thanks for your response. I have done that already but I wanted the data I retrived for that id to be passed to TabPersonal. After searching for a while I have come acrossed FindControl. But it gives null reference exception. Here is how I am trying to pass the data to TabPersonal.

Dim txt As TextBox = Nothing

txt = Master.FindControl("cntContractorEdit").FindControl("TabContractor").FindControl("TabPersonal").FindControl("txtContractorNumber")
txt.Text = dr("ContractorNumber")

I don't see a control named "txtContractorNumber" being declared within the TabPersonal container. If you actually intend to use the txtVenderNumber control, then you would use the following command:

<pre>
txtVendorNumber.Text = dr("ContractorNumber")
</pre>

You don't need to use FindControl when using ASP.Net Controls.
